Sunset Crater Volcano National Monument

So about 15 minutes northeast of Flagstaff is Sunset Crater Volcano National Monument.  It is the cinder cone of a volcanic explosion from about 900 years ago.  We explored the base of the cone and I climbed out onto the remains of the lava flow.

The lava flow came off the volcano and cooled and solidified near the base of the cone... 900 years later a few pine trees have managed to take root in the rocks...

And finally, here is me in full social studies teacher attire climbing out onto the lava flow rocks...  Who says you can't hike in dress shoes?
